This is the script extraction/re-insertion tool for Complets's games.  It requires the python programming language to be installed. The batch files require you to put the python directory (like c:\python31) in your PATH environment variable.

files:
extract.bat - extracts text versions from all mpx files.  Will overwrite your work, so don't run it more than once.
update.bat - Inserts txt files into the MPX files.
update2.bat - Inserts txt files into the MPX files, and writes them to the ..\mpx directory.

Recommended use: 
Copy the MPX directory to a new folder, like "mpx_translated" or something.
run extract.bat, rename it to something else so you don't lose your work by mistake.
Delete update.bat.
Run update2.bat to test out your new script.


Brief MPX file format "encryption":
If you take an MPX file and XOR every byte with 0x24, you can get a readable version of the file where you can hex-edit the text.  But there are some pointers to places in the file (such as for menus), so use the code of mpxtool for more information on the file format.
